摘要： A fuel vapor treatment apparatus includes: a detection passage provided with a restrictor therein; a pump generating a gas-flow in the detection passage; and a differential pressure sensor detecting a pressure loss at the restrictor. A fuel vapor concentration is computed based on a pressure loss when air passes through the detection passage and a pressure loss when an air-fuel mixture passes through the detection passage. When the computed fuel vapor concentration reaches a specified value, an internal combustion engine is started and the fuel vapor treatment apparatus starts to supply the fuel vapor adsorbed by the canister to the internal combustion engine.

摘要： A detector for detecting evaporated fuel leakage from a fuel tank is connected to the fuel tank through a canister for absorbing evaporated fuel. When an engine is not in operation, air in the fuel tank is sucked by a pump installed in the detector. If the pressure in the fuel tank decreases to a predetermined level, it is determined that the evaporated fuel leakage is within a permissible range. An orifice passage, formed in the detector, connecting a tank passage to a sensor passage communicating with a sensor chamber where a pressure sensor is disposed is slanted relative to the tank passage to shorten the passage distance up to the pressure sensor. Further, the orifice passage is connected to the sensor passage at an obtuse angle to reduce a pressure loss in the passages. Thus, the leakage of the evaporated fuel is surely detected while making the detector compact.

摘要： When detection of an abnormality in a fuel vapor treating system is executed, a vapor zone including a fuel tank and a canister is sealed. The sealed vapor zone is pressurized. Whether fuel vapor is leaking from the vapor zone is determined based on the pressure in the sealed vapor zone. A canister valve selectively connects a canister with and disconnects the canister from the atmosphere. During the abnormality detecting procedure, an electronic control unit (ECU) shuts the canister valve. After the abnormality detecting procedure is ended, the ECU sends a control signal having a predetermined frequency to the canister valve, thereby gradually increasing the opening size of the canister valve. Accordingly, the pressure in the vapor zone is gradually lowered to the atmospheric pressure. This prevents fuel vapor adsorbed by the canister from being released to the atmosphere.

摘要翻译： 当执行燃料蒸汽处理系统的异常检测时，密封包括燃料箱和罐的蒸气区。 密封的蒸气区被加压。 燃料蒸汽是否从蒸汽区泄漏是基于密封蒸气区中的压力来确定的。 罐阀选择性地将罐与大气连接并将罐与大气隔离。 在异常检测过程中，电子控制单元（ECU）关闭罐阀。 在异常检测步骤结束之后，ECU向罐阀发送具有预定频率的控制信号，从而逐渐增加罐阀的开度。 因此，蒸汽区中的压力逐渐降低至大气压。 这防止了由罐吸附的燃料蒸气被释放到大气中。

摘要： Stable receiving action is achieved with a receiver of simpler configuration.When a human hand is held over the panel unit 201, the electric field in the vicinity of the human body is coupled to the sensor electrode 2122 of the coil sensor 212 from the receiving electrode 211 of the panel unit 201, and alternate current is generated at the sensor electrode 2122. This alternate current then induces a magnetic flux inside the central opening of the coil 2121 in proportion to the strength of the electric field in the vicinity of the human body. Depending on the changes in this magnetic flux, electric current passes through the coil 2121. The electric current passing through the coil 2121 is converted by the electric current detecting circuit 2124 of the coil sensor 212 to voltage signals and transmitted as received signals to the demodulator 22. As a result, the received signals corresponding to the electric field in the vicinity of the human body, namely the transmission signals applied by the transmitter 1 to the human body, are obtained.

摘要： An observation apparatus is provided. An apex angle of a contact prism is inputted by operating an apex angle setting knob of a control panel. A fining angle of the contact prism is inputted by operating a fitting angle setting knob. A control unit determines the amount of correction for astigmatism of a left observation optical system and the amount of correction for astigmatism of a right observation optical system based on a recognized observation magnification and the inputted apex angle. An axial angle for the astigmatism of the left observation optical system and an axial angle for the astigmatism of the right observation optical system are determined based on the inputted fitting angle. Variable cross cylinder lens rotating drive units are controlled to rotate cylinder lenses of each of the right and left observation optical systems, thereby obtaining the determined axial angle and the determined amount of correction.
